Area Forecast Discussion National Weather Service Memphis TN 624 AM CDT Mon Aug 28 2017 .DISCUSSION... Updated for 12z Aviation Discussion. && .PREV DISCUSSION... /issued 342 AM CDT Mon Aug 28 2017/ DISCUSSION... Currently...A weak cold front and shortwave are moving into the NW part of the forecast area this morning. A few thunderstorms have developed across Randolph and Lawrence counties. Otherwise mid level moisture from Harvey continues to spread over the region with a few sprinkles across North Mississippi. Temperatures range from the mid 60s along the KY border to lower 70s across much of the remainder of the area. Today through Tuesday...An upper low will track across the southern Great Lakes with troughing extending into the Mid-South. A weak cold front will slowly track across the Mid-South today and tonight then stall and weaken further on Tuesday. Expect scattered showers and thunderstorms to develop today. Temps should be a couple of degrees cooler with more clouds and precip. Activity should diminish in the evening with loss of heating and the upper trough starting to pull east. Should see less activity on Tuesday as the upper trough continues to pull away. Temps will be couple of degrees warmer. Wednesday through Sunday...Models have started to trend back toward bringing the remnants of Harvey north toward the Mid- South. 00z guidance is still all over the map but the ECMWF and several GEFS members track the circulation into the region. As a result the risk of heavy rain over parts of the Mid-South is increasing. At this time is appears the best chances would be over eastern AR but confidence in the placement of the heaviest rain is low giving the high variability in model solutions. Most solutions are indicating somewhere in the neighborhood of 2 to 6 inches across the Mid-South through the weekend. Have increased pops during this time period and will place the threat of heavy rain in the HWO from the Wed through Sunday. Temps will be below normal through the period. SJM && .AVIATION... 12Z TAFs Convection expected throughout this TAF period for all sites. Tried to narrow down the best timing...but confidence is low as moist environment could lead to multiple rounds throughout the day and evening. Conditions likely to briefly drop to MVFR or IFR in heavier downpours. Coverage and intensity should let up late in the period. Winds outside of storms will be southerly at 3-7kts. Light fog potential late at MKL. JAB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
